平板光生物反应器光径对金藻生长及有机物质积累的影响积累的影响（英文）

目的]为金藻（Isochrysis galbana Parke）的大规模培养、药用研究及开发利用提供参考。方法]在不同光径平板生物反应器中培养金藻,并对藻细胞的生长状况和细胞内的有机物质含量进行了分析。结果]藻细胞的生长速率及单位体积产量随光径的减小而增大;单位面积产量随光径的增大而增大;光径越小的生物反应器中培养的金藻藻细胞内的总脂、蛋白质及多糖占细胞干重的总量越高。结论]根据生产需要选择合适的生物反应器,可有效提高生产效率、降低生产成本。

Effect of Flating Photobioreactor Light-path on the Growth and Organic Matter Accumulation of Isochrysis galbana Parke

Objective] The paper aims to provide references to cultivate I.galbana in a large scale and explore its medical value.Method] I.galbana had been cultivated in different light-path flat plate bioreactors,and the growth condition and content of organic matter within cells of I.galbana had been analyzed.Result] Growth rate and volumetric productivity of I.galbana cells increased as light-path of flat plate bioreactors decreased,however,daily areal output rate rose with the increasing of light path.The smaller the light path of flat plate bioreactors was,the more content of total lipids,protein and polysaccharide it had in I.galbana cells.Conclusion] It is an effective way to improve production efficiently and reduce the cost by selecting the suitable bioreactors.
